A single donkey, usually a jennet, sometimes a gelding (jacks rarely work because they can be too aggressive with lambs) is introduced to the herd and undergoes a bonding stage. After it has bonded with the sheep, it will protect them against canine predators (fox, coyote, dogs) as it would one of its own.any people like to own these fine animals for their wonderful personalities and their fine pet qualities. There is probably no more adorable baby in the animal world than the little donkey with its long ears and long legs and sweet face and fuzzy coat. However, there are many uses for donkeys.
